When using page preview in Calc, it would improve usability if landscape or portrait page orientation could be directly changed in the preview window (and not via opening the "Format page" window and clicking on -> Page -> Orientation").
Please add buttons for "Landscape" and "Portrait" in the preview window.
Changing page orientation is likely one of the most often applied preferences when printing a spreadsheet. The other often used settings are already directly accessible in the page preview window and are nicely implemented: The Zoom Slider and the adjustment of Margins. Only page orientation is missing.

Yes, it would be preferable to switch between landscape and portrait.
Print preview is a read only mode, we would likely need to create uno commands that work in that mode to change the page orientation. We have the .uno:Orientation group button that is available in the notebookbar, but it is only usable in writer and is disabled in print preview mode.
@Szymon: Any thoughts?
